I don’t think he is a sure thing. He will most likely lose the general, or it will be close enough for the Dems to steal it through fraud.
There won’t be enough fraud to take out Donald.
*sigh*
Democrats don't cheat, fight voter ID laws tooth and nail, promote policies (such as Motor Voter) that make it easy for illegals to vote, etc. etc. etc., just to hedge their bets.
They cheat because if they didn't, they'd LOSE. Believing the myth that cheating only works for them "when it's close" is defeatist and ultimately guaranteed to aid and abet Democrat fraud.
